I have a P90DL with about 2K miles. I'm trying to learn as much as I can about how the car works so that I can care for it properly while enjoying it to the fullest. Recently I noticed that when I engage the accelerator after it has been in reverse or regen, I feel a small, silent "bumb" before acceleration begins. I've driven manuals all my life and it feels like the gear play you experience going between engine braking and acceleration. I think most people wouldn't even notice it, but I (to my detriment sometimes) am hyper-aware of what I feel, hear, and smell from my cars. To the gearheads, is this normal "break-in"? My concern is that "any" play might accelerate the condition because of the motors' ludicrous torque. My hope is that the single speed transmission, being much simpler than a typical multi-speed transmission, would be more robust and able to take the abuse from the motors. I would especially like to hear from other "P" owners that have some time and miles on their S. Thanks.
